> as I said, that's the ctypes problem, weird is I don't get this specific problem, when I compile it, I get  PORT_LONG_MAX = 2147483647 (without the L)

On my Fedora 28 box, I get

[mneteler at oboe ctypes ]$ pwd
/home/mneteler/software/grass77/lib/python/ctypes

[mneteler at oboe ctypes ]$ ag PORT_LONG_MAX
OBJ.x86_64-pc-linux-gnu/vector.py
6562:    PORT_LONG_MAX = 2147483647L
7256:    PORT_LONG_MAX = 2147483647L

where PORT_LONG_MAX is mentioned.
